Microstructure of cobalt chromium alloy in cast condition is______________?
Correct answer: C. Inhomogenous
- A. Fibrous
- B. Homogeneous
- C. Inhomogenous
- D. amorphous
Explanation
Cast cobalt-chromium alloys commonly show a dendritic, compositionally segregated microstructure, so the structure is inhomogeneous. A homogeneous or amorphous structure would not describe a normally solidified cast alloy.
